Benefits of technology

[0006] In another aspect of the invention, a catheter cuff includes a combination of collagen and polymeric material is implemented to improve hemostasis and accelerate tissue ingrowth. For example, the cuff may include a polyester felt with embedded Avitene® collagen. In another variation, the cuff includes a polymeric base layer with interwoven Avitene® collagen filament. In yet another variation, the cuff includes two or more layers of materials. In one combination, an inner layer is free of collagen, while an outer layer includes a collagen material. A scrim or separation layer may be provided between the two layers to isolate the collagen material from the inner layer, or prevent the adhesive from the inner layer from encroaching the outer layer.

Problems solved by technology

In addition, the collagen cuff may also induce tissue ingrowth.

Abstract

Implantable catheters including one or more cuffs are described herein. At least one of the cuffs may include a collagen material, such as Avitene® collagen. The catheter may include a combination of collagen cuffs and collagen-free polymeric cuffs. Various methods for the fabrication of collagen cuffs are also disclosed herein.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit under 35 U.S.C. § 119(e), to U.S. Provisional Application No. 60 / 639,051, filed Dec. 21, 2004, which is incorporated by reference into this application as if fully set forth herein.BACKGROUND OF THE INVENTION [0002] Various approaches have been developed to facilitate hemostasis and / or to accelerate tissue ingrowth in order to improve the securement of an implanted catheter within the bodily tissue. In one common approach, a catheter cuff is provided along the length of the catheter to stabilize the position of the catheter within the implanted tissue. For example, the catheter cuff may serve as an interface for tissue ingrowth to stabilize the implanted catheter within a subcutaneous tunnel. The catheter cuff may also prevent infectious agents from migrating along the length of the catheter into a patient's body. [0003] It is common to position a proximal portion of an implanted catheter in a subcuta...
